When learning PHP, it is often used to get the date before or after a certain time period. Now it's collected and you can expand it
Copy CodeThe code is as follows:
Get the day of the Week (1-7)
function Getweek ($times)
{
$res = Date (' W ', Strtotime ($times));
if ($res ==0)
$res = 7;
return $res;
}
Get the time of day
function GetTime ($times)
{
$res = Date (' H:i ', Strtotime ($times));
return $res;
}
Get the time in a few months now
function GetMonth ($Month, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$Month months"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $Month months"));
return $res;
}
Get current time
function GetCurrentDateTime ()
{
$res =date ("y-m-d h:i:s", Time ());
return $res;
}
Gets the time before or after the current time interval
function Getdiffhours ($hours, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$hours Hour"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $hours Hour"));
return $res;
}
Interval a few minutes before or after the time
function Getdiffminute ($Minute, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$Minute Minute"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $Minute Minute"));
return $res;
}
Interval a few seconds before or after the time
function Getdiffsec ($sec, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$sec Second"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $sec Second"));
return $res;
}

Interval a few weeks before or after the time
function Getdiffweek ($Week, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$Week Week"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $Week Week"));
return $res;
}
Time interval between days
function Getdiffdays ($days, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$days Day"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $days Day"));
return $res;
}
Time before or after a few years
function Getdiffyears ($year, $type = ' l ')
{
if (!strcmp ($type, ' B '))
$res =date ("y-m-d h:i:s", Strtotime ("-$year Year"));
if (!strcmp ($type, ' l '))
$res =date ("y-m-d h:i:s", Strtotime ("+ $year Year"));
return $res;
}
